In addition to this
My turbo seized but not due to this - it seized from build up of carbon in
the hot side - which I gather is pretty weird. After cleaning it worked
fine.
The guy who runs the shop here says that it is a result of reducing power
quickly - and that to avoid this, on all turbos one should reduce power
slowly.

You run the engine to reduce the turbo bearing temperatures, If you shut
down quickly after working the engine hard there is a risk of turning the
oil to carbon and destroying them over time,
Once the engine is shut down the oil ceases to flow through the turbo
bearings,

Was you using predominantly Avgas 100LL or Unleaded ?
After many years working on turbo engines Both Petrol and diesel, I have
had turbine`s go badly out of balance due to carbon build up,
They makes a loud whistling noise, But never enough to seize, At least
that's better than the waste gate seizing and causing a overboost,

100ll - because the premium mogas in Colombia where I live is only 91
octane.

Thanks for that,! Another good reason to use unleaded if you can.

Yup think so - the engine as I understand it is designed for European
premium mogas

Almost correct. It's intended to use European _standard_ mogas (95 Octane,
often referred to confusingly as 'premium', but North American folks please
we aware we measure Octane differently, quoting higher numbers for the same
stuff). The _premium_ stuff (97 to 98, often called 'super') is not
recommended for use in aircraft (some volatility issues at altitude, I
believe).
As an aside for the UK folks, rumours are currently rife that Shell is about
to release V-Power here instead of the current Optimax - which means 99 or
100 Octane for your sports cars.

Jeremy
